A set of 64 sorghum genotypes was evaluated for adaptability and stability in three environments during rabi 2020-2021. The regression method of stability analysis was used to study grain yield adaptability and stability. Results revealed that, genotypes, environments, G × E interaction, and G × E (linear) all differed significantly. Hybrid SG-16 (2.78 kg/plot) was identified as the highest yielding. Based on the regression coefficient (bi) and deviation from regression (s2di) scores, the high-yielding hybrids, namely, SG-26, SG-16, SG-3, SG-29, and SG-6, were found to be stable and adapted to a wide range of environments.
